The ceil of the scalar x is the smallest integer i, such that
i >= x. It is often denoted as .

Parameters:

x:array_like

Input data.

out:ndarray, None, or tuple of ndarray and None, optional

A location into which the result is stored. If provided, it must have
a shape that the inputs broadcast to. If not provided or None,
a freshly-allocated array is returned. A tuple (possible only as a
keyword argument) must have length equal to the number of outputs.

where:array_like, optional

This condition is broadcast over the input. At locations where the
condition is True, the out array will be set to the ufunc result.
Elsewhere, the out array will retain its original value.
Note that if an uninitialized out array is created via the default
out=None, locations within it where the condition is False will
remain uninitialized.
